SYRINGE.

To @7l whom 'it may concern:

Tie `it known that I, Josnrlt J. Bam, a citizen ot' the United States, residing at (lhicago, in the county ot Cook and State et lllinois, have invented certain new and usetul Improvements in Syringes, of which the following is a spixcitication.

My invention relates in general to syringes, but pertains more in particular to a syringe havil'ig a series ot adjustable, expanding and contracting fingers, in combination with a spray tube and bulb member, whereby the walls ot the vagina and other internal organs may be easily dilated and cleansed and the fingers then contracted and withdrawn without injury to the membrane tissue.

The main objects ot the invention are to provide an improved means 'tor e tl'ecting irrigation of.2 the organs, tor securing better hygienic sanitation, and ttor increasing the etficiency ot medicinal application by properly cleansing the parts ot disease s-ecretions.

Other objects ot the invention are to provide an ett'ective syringe that 'is easily operated; to provide a syringe that is capable et being quickly and thoroughly cleaned; to provide an adjustable syringe the fingers ot which may be shortened or lengthened, and to simplify and reduce the cost oit production of articles of this character.

Further advantages oit the invention will appear throughout the specification.

In the accompanying drawing,-l l`igure l is an elevational view ot' the device partly in central longitudinal section. Fig. Q is an end view oit the chambered body member ot' the syringe with the cap or cover thereoitl re moved. Fig. 8 is a section on the line 3MB et' Fig. i3. Fig. i is an inner t'ace view ot the cap or cover ot the body n'leinber, with the spray tube to which it is secured shown in cross-section. Fig. is an end view ot' the syringe, with the fingers in contracted position. Figs. G and 7 are detail end and perspective views o'f' the nozzle. and sprayplug there't'or, respectively; and vFigs. S and t) are edge and side views, respectively, ot the inner ends ot the fingers, showing an alternative securing means there'for.

Referring now more particularly to the drawing, it() represents the body member of. the device, which is preferably con'iposed ot hard rubber, having a conical or tapered end 10:L for substantially one-half of its Specification of Letters Patent.

length, the remaining halt l0 being cylindrical and hollow in cross section to torm the chamber 1l. rlhe tapered end itl has formed therein linger receiving apertures l2. The apertures 12 are tapering` the inner walls l2 being arranged substantially parallel with the axis ot' the body member, while. the outer walls l2" diverge Atrom the inner walls to 't'orln a wide mouth to the apertures where they open into the circular chamber l1. The tapered end l0 is provided with a tube-receiving axial bore Alil; and an annular guide member l-t, ot equal internal diameter with thc diameter ot the bore l il, is secured to the body member `within the chamber ll; the inner walls ot? both guide and bore heilig' in alinement.

Slidably mounted on the guide member 1-lis a sleeve '15. split longitudinally, as shown at l5LL so as to be transversely elastic and provided with a series o'f perlhrations or apertures ,15" adjacent to one o'lE its longitudinal edges. Notehes l5" are tormed at the ends ot" the disk guide member 15, 'tour notches heilig pre't'erably `tormed at each end. which constitute thc 'female members ot a clutch mechanism which `will be hereina'tter described. Adjustably mounted upon said sleeve 'l5 is a cam member or disk lf3 having eccentric slots ltL formed therein. the purpose ot' said slots being herea'liter described.

An apertured spray tube 17 extends through the body member l() having a nozzle 17 secured thereto in any suitable manner, or 'formed integral therewith, suitable apertures A1.71J being formcd therein that communicate with the interior o'tl the tube. The t'ree end ot the nozzle is provided with a threaded opening' [S terminating in a flared mouth lt) having a series of grooves itl termed on the. flared surface. A Isolid plug 20 having threaded prongs 20 cooperating `with the threaded aperture its is adapted to partially close said aperture whereby any liquid 'forced through said spray tube will be 'forced through said apertures i7" and grooves 1911 around said plug. The other end Q1 ot said spray tube is preterably curved and a bulb 2i). ot the. ordinary charactcr is connected therewith.

The expanding and contracting fingers 23 are bowed at the outer ends, which g'ne'terably extend beyond the end ot the nozzle, the A in the following manner. Spring tongues 23 are secured to the inner ends of the lingers 28 en the inner sides of the latter in such a manner that the free ends of the tongues lie normally separated from the ends of the lingers. Small lugs or swells 23h are pressed or otherwise formed on the inner ends of the lingers on the outer sides thereof;

and when the spring tongues are pressed against the ends of the fingers both may be forced into the eccentric slots 16ZL whereupon by releasing the tension on the tongues one edge of the slots is confined between two adjacent lugs 23h and the fingers and disk 16 are thus united in such manner that the disk may have a rotating movement relative to the fingers, but is locked against a longitudinal movement relative thereto. 1n Fig. 1 the lingers are shown as extended their full lengt-h, but when it is desired to shorten them the fingers may be moved longitudinally relative to the disk 16 by compressing the spring tongues 23a so that the disk will lie between any inner adjacent pair of lugs or swells (23h). A further manner of adjusting the fingers as to their length is by adjusting the disk 16 longitudinally of the sleeve 15; a projection Q4 of the disk being adapted to enter any one of the perforations 15b. a still further manner of adjustmentjwould be to invert the sleeve 15 and disk 16, so as to bring the disk 16 nearer the open end of the body member. This latter form of adjustment could be accomplished without moving the disk longitudinally, relative to either the sleeve or fingers. The expanding or contracting of the fingers is effected b y means of the movable end cap Q5 of the body member in the following manner. The open end of the body member is formed with a laterally projecting lug 26 and diametrically opposite the same is a spring tongue 27 secured to the inner wall of the chamber of the body member and formed at its outer end with a similar laterally projecting lug 26a, said spring tongue having a button 27a projecting through a suitable aperture in the body member. The cap or cover 25 is formed with an inwardly turned iiange Q5, which, by depressing the spring 27, is readily engaged and interhooked with the lugs 26 and 26, in the manner shown in F ig. 1, so as to be capable of a rotary movement relative to the body member 10. The cap 25 is centrally apertured to fit the spray tube 17 and is soldered or otherwise secured to the latter'. Said cap is further provided with one or more apertures 25" around the spray tube, the purpose of which is to permit a free return of the water discharged by the spray tube. 0n the inner face of said cap is also located an annular series of lugs Q8 constituting the male members of a clutch mechanism adapted to interlock and coperate with the notches 15c in either end of the sleeve 15. 1t will thus be seen that a turning movement of the cap relatively to the body-member 1() effects the rotation of the sleeve 15 on which the cam disk 16 is mounted, causing the latter to turn. rEhe turning movement of said disk, through the engagement of the cam slots 16a with the inner ends of the fingers, effects a rocking or tipping movement of the latter, a movement of the disk in one direction causing the inner ends of the lingers to approach the axis of the cam so as to produce an expanding movement of the projecting portions of the fingers, and an opposite movement of the cam disk resulting in corresponding opposite movements of the fingers.

1 am aware that a rotary disk having cam grooves coperating with the ends of the lingers has heretofore been proposed, but the provision of a cam disk with eccentric slots has mnnerous advantages thereover in positively securingthe lingers against longitudinal displacement, as well as permitting the described adjustments of the fingers, and the easy cleaning of the device.

ln Figs. 8 and 9, 1 have illustrated a modi fication in the means for detachably locking the inner ends of the fingers in the cam disk 16. 1n this form the inner ends of the lingers 3() are longitudinally split for a short distance, as at 31, thereby forming a central tongue 32 having the lugs or swells 33; and, on either side thereof, integral bow springs 34, which have the same function as the springs 23a above described.

1t is, of course, obvious that the degree of lateral movement of the lingers may be regulated entirely by the curva-tures given to the eccentric or cam slots. 1t can thus be readily seen that a movement of the cap (25) readily effects the expanding or contracting of the fingers; and as t-he lingers are adjustable, as to their length, in any of the several ways indicated, it follows that the instrument is capable of very fine adjustment as to length. The individual parts are few in number and are readily assembled and taken apart for purposes of adjustment or cleaning. In this connection l may mention that by unscrewing the end plug 2O of the spray nozzle, the entire bore of the spray tube is left free and unobstructed, which greatly facilitates the cleaning out of the latter.

Numerous other advantages will be appar ent to those skilled in the art; and therefore, without limiting myself to the precise details shown and described, 1 claim:

1. 1n a syringe, the combination with a hollow body member and a spray tube extending axially therethrough, of a series of distensible fingers surrounding said spray tube, a sleeve rotatably mounted in said body member, a cam disk carried by said sleeve and a rotatable cap closing the outer end ot said hollow body member, said ap and the adjacent end otA said sleeve being provided with cooperating clutch members, substantially as described.
